Part Number: DRV8870 Hello!
I am a newbie at DRV8870 Motor Driver.
I am going to connect unregulated dc24v to the VM pin of DRV8870 like as below schematic.
Would you please let me know whether there is some problem or not?
Your response would be highly…
Part Number: DRV8870 I'm using a DRV8870 in order to provide a bidirectional drive for a DC motor, but I also need one of the output lines to idle high when both inputs are low (DRV8870 is in sleep mode). I thought that this would be permissible as the…
Part Number: DRV8870 Hi Team,
Customer would like to know can the DRV8870 achieve high torque and high current when it is started, and low torque and low current during operation? Is there any way to achieve this using this chip? There is a current limiting…
Part Number: DRV8870 Hi Team,
Please refer question on waveform as below:
When both IN1 and IN2 are set to low logic, the device working on low side recirculation. Why there is positive 4V on OUT1? If there any current flowing, there is 0.7 voltage drop…
Part Number: DRV8870 Hi Team,
My customer is considering an Earth fault detection circuit for a motor output line.
In the attached circuit configuration, the Absolute Maximum Rating (VM +0.7V) of the OUT pin is exceeded when VM=0V.
A few mA will flow…
Part Number: DRV8870 In a new Project we are developing we are using DRV8870 Motor Driver from Texas
In the first test done we´ve had problems in 2 units where the driver was broken doing hot plugs and unplugs.
We have followed the recomendations…
Part Number: DRV8870 Other Parts Discussed in Thread: DRV8873 , DRV8256 , DRV8874 We are using the DRV8870 driver in our design. We are running into the thermal limit and are looking for a lower RDS(on) option. One of our engineers mentioned that maybe we…
Part Number: DRV8870 Hello Team,
Good day.
My customer is using DC motor driver DRV8870 with brushed dc motor. They found the motor induced electrical noise over its supply lines (between the commutators). They wanted to know if it is allowed to connect…
Part Number: DRV8870 Hi
As we can see from our datasheet, the Absolute maximum ratings of Pin OUT1 and OUT2 should be greater than -0.7V, but we found it less than -0.7V during test(waveform as below), could you please recommend how long DRV8870 can operate…
Part Number: DRV8870 Hi Sir /Madam
I use the chip of DRV8870 , and connect my motor as picture, but it can not workable (don't run, just a little noise)
motor no. RS-380ph
power supply , 7.5V 2A
Pls help to check it, thanks
